"the Prius c’s EPA-estimated fuel economy ratings of 53/46 mpg city/highway are the highest of all small hybrids, and the 53 mpg city rating is the highest rating for any vehicle without a plug."
Well, that beats the EPA highway 46 MPG number, and then some! Since a lot of folks aren't going to be driving an average of
70 MPH..
Seems like you might be able to do a lot better if you made that trip under the speed limit..
Next time, get up early and set the cruise control to 55..
I see it was warm, did you use the AC at all? And, were you in Eco mode?
